django+drf+nginx+uwsgi+socket项目部署
准备centos 7服务器一台
后端代码
前端代码
- 在/var/www/目录下创建项目文件夹,例如创建house_statistic_query_dev如下
[root@lidong www]# pwd
/var/www
[root@lidong www]# ls
house_statistic_query_dev
- 将前端项目，后端代码项目放到house_statistic_query_dev里，并创建配置文件夹(dev_config)
[root@lidong house_statistic_query_dev]# pwd
/var/www/house_statistic_query_dev
[root@lidong house_statistic_query_dev]# ll
total 4
drwxr-xr-x. 4 root root 105 Nov 19 09:03 dev_config
drwxr-xr-x. 14 root root 282 Nov 17 03:27 house_statistic_query_backend
drwxr-xr-x. 10 root root 4096 Nov 19 07:09 house_statistic_query_front
- 在dev_config文件夹下创建uwsgi文件夹，venv虚拟环境
[root@lidong dev_config]# pwd
/var/www/house_statistic_query_dev/dev_config
[root@lidong dev_config]# ll
total 12
drwxr-xr-x. 2 root root 70 Nov 23 02:04 uwsgi # make uwsgi
drwxr-xr-x. 6 root root 92 Nov 17 03:26 venv #执行python -m venv venv完成创建
- 激活虚拟环境
[root@lidong ~]# source /var/www/house_statistic_query_dev/dev_config/venv/bin/activate
(venv) [root@lidong ~]#
- 进入项目目录，检测该Django项目目录是否能够正确启动
(venv) [root@lidong house_statistic_query_backend]# python3 manage.py runserver 172.16.10.239:8833

如果DEBUG = True,浏览器访问你应看到：

- 在uwsgi文件夹下创建uwsgi.ini文件
[uwsgi]
# 如果我们想直接将uwsgi用作服务，直接暴露在公网那么就使用http；
# 如果有单独的服务器，由服务器将请求转发给uwsgi处理，并且使用http协议，那么此时使用http-socket
# http的端口，http 一般是作为独立部署的选项; http-socket 在前端webserver不支持uwsgi时使用,
# nginx的端口，前端webserver支持uwsgi, 则直接使用socket即可(tcp or unix)
#http= :8081
socket=:8082
http-keepalive=1
# 项目所在的目录
chdir=/var/www/house_statistic_query_dev/house_statistic_query_backend
# wsgi所在的位置(django项目的wsgi.py文件)
module=house_statistic_query_backend.wsgi:application
# 替换uwsgi.py文件下的os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'house_bi.settings')
env = DJANGO_SETTINGS_MODULE=settings.dev
# 设置静态文件
# static-map = /ui=/var/www/house_statistic_query_dev/house_statistic_query_backend/static
# 启动主进程
master=true
# 进程个数
workers=3
# 在每个worker而不是master中加载应用
lazy-apps=true
# 每个进程最大请求个数
max-requests=2000
# 启动uwsgi的用户名和用户组
uid=root
gid=root
# 自动移除unix Socket 和 Pid 文件 当服务停止的时候
vacuum=true
# 启用线程
enable-threads=true
# 设置自中断时间
harakiri=30
# 设置缓冲
post-buffering=4096
# 序列化接受的内容，如果可能的话
thunder-lock = true
buffer-size = 65536
# 进程个数
processes=4
threads=2
chmod-socket=664
pidfile=/var/www/house_statistic_query_dev/dev_config/uwsgi/uwsgi.pid
#日志所在位置
logto=/var/www/house_statistic_query_dev/dev_config/uwsgi/uwsgi.log
注意：当连接为socket通信时，不需要设置static-map对应的静态文件路径，因为此时使用外部浏览器将无法直接访问，会提示类似于“缓存区(buffer)超过最大长度”类似的问题。故所以需要nginx来转发，因为nginx服务器和后端可以用socket连接，故需要先访问uwsgi服务器，再请求后端服务器
- 使用uwsgi启动django服务器，会生成四个文件如下。
(venv) [root@lidong uwsgi]# uwsgi -d --ini uwsgi.ini
[uWSGI] getting INI configuration from uwsgi.ini
(venv) [root@lidong uwsgi]# ll

- 查看是否启动成功，出现该网页无法访问则为启动成功
- 下载nginx，并配置nginx.conf文件如下，并启动nginx
- 方法一：配置，对应uwsgi.ini文件中的uwsgi.sock文件路径
- uwsgi_pass unix:/var/www/house_statistic_query_dev/dev_config/uwsgi/uwsgi.sock;

- 检查是否配置成功，此时静态文件可以正常加载。
- 检查是否与后端连接成功，检查登陆功能。
